LEVELING DEVICE.

Application filed April 9, 1926.

This invention relates to leveling devices and in particular to a deviceadapted to level up billiard or game tables, and to anchor the samesecurely to the floor. 5 A particular object of the invention is toprovide a convenient means whereby the legs of a table, particularly abilliard table, may be adjusted to level the table as is necessary inthe playing of games.

A further object of the invention is to provide a simplified tableraising mechanism which can be operated to adjust the height of all ofthe corners of the table comprehend the underlying features out ourinvention that they may embody the same in the various modifications instructure and relation contemplated, drawings depicting a preferred formhave been annexed as a part of this disclosure and in such drawingssimilar reference charactersdenote corresponding parts throughout all ofthe Views, of which,

Figure 1 is a view in side elevation of a billiard table or'other likegame table, having incorporated in the legs thereoi our improvedleveling device and Figure? is an enlarged sectional detailed view takenon the line 2- 2 of Figure 1 showing the construction and operation ofour improved leveling device.

referring to the drawings in detail 5 indicatesthe body or bed of abilliard-or other game table oi heavy construction having the supportingleg members 6. llt has always been a problem to accurately adjust abilliard table so that the surface thereof. is perfectly level and inorder to do this various means have been resorted to, such for instance.as putting small blocks under the legs of the table and other suchdevices that will bring the table at the corners thereoi to the requiredheight to make the bed of the table perfecly level, so that balls orother game. pieces thereon will have freeand unrestricted movementsthereacrosss, and to Serial No. 100,965.

this end we provide in each of the legs 6 of the table a centrallydisposed inwardly extending bore 7, the upper end of which terminates ina bore 8 of substantially smaller diameter in which is adapted to beheld the internally threaded sleeve member 9, which is provided at itslower end with a flange 10, through which are adapted to pass. the woodscrews 11 whereby the flange 10 will be bound against the inner end otthe bore 7 and the sleeve 9 will be held sei ely in place within thebore 8. This L e *e inen'iber 9 has operating through the -rnallythreaded bore 12' thereof, the

threaded end 13 ot' a ack screw 14: the lower end oi. which passesthrough a beveled gear 15 and is secured thereto, through the medi um oithe set screw 16 carried by said bevel gear 15. The jack screw 1% isjournaled at its lower end in a suitable base 17 which is preferablyformed integral with a base plate 18 and is of substantially the samediameter as the internal bore 7 in the table legs whereby the lower endof the table will have sliding movement loi'igitudinally of said base 17and will he guided thereby in its vertical movement. The base plate 18may be square or round, depending upon the shape of the table legs (5and said base plate is of substantially the same diameter as the loweredge of the table legs and forms therefore a support upon which thetable leg rest-s when the same is in its lowered position. The baseplate 18 may be suitably secured to the flooring 19 by the screws 20.

The base 17 is provided at one side with an upstanding bracket 21 whichforms a hearing at its upper end as at 22 for the pin ion carrying shaft23, which is journaled therein and which carries at its inner end thepinion 24 WlllCll meshes with the beveled gear 15. The outerend ot thepinion carryingshatt is squared as at 25 so that it may be engaged by asuitable socket wrench for manipulation, the end of the shaft beingdisposed in a suitable opening 26 formed in the legs of the tableadjacent the bracket and arranged so that a socket wrench orv brace canbe applied to the shaft 23 to cause operation of the beveled gear 15through the pinion 2a to cause operation of the jack screw in the sleeve8 to raise or lower the table as desired.

It will be evident therefore that we have provided an improved tableanchoring and (ill leveling device which can be manipulated to give afine adjustment in the height of one corner ofthe table and which asshown by the dotted line 27, in Figure 1, can be arranged to bring thetable down or up to a perfectly level position.

It is also evident that we have'provided for heavy tables, such asbilliard tables, a

suitable adjusting device which can be of-the appended claims.

Having thus described our invention what we claim as new and desire tosecure by United States Letters Patent is:

1. The combination with the leg of a table having a bore in the lowerend thereof and an opening adjacent said bore, of an elongated sleeve inthe bore fixed to said leg, a screw operable in said sleeve, meansdisposed in said openii'ig for operating said screw to cause verticalmovement of the table, a base for keeping the screw in verticalalignment, the base having an upwardly disposed extension which fitssnugly within the bore and serves as a guide for the leg during itsmovement and an extended foot portion on said base adapted to be securedto the floor to form an anchor for the table and a bracket associatedwith the base and arranged to support the screw operating table having abore in the lower end thereof and a. reduced bore extending further intothe leg ofthe table, of a flanged, elongated, internally threaded sleeveseated in said BX"; tended bore, a screw operable in said sleeve, a basein which the lower end of the screw is journalled, said base having afoot portion upon which the lower end of the table leg may rest andhaving an upwardly projecting portion adapted to fit into the lower boreof the leg to guide the vertical movement of said leg, a bracket on saidprojecting portion, a gear combination carried by the bracket and thescrew through which the latter can be operated to raise and lower thetable, and means for fastening the base loot portion to the floorwhereby the same formsan anchor for the legs of the table.

A leveling and anchoring device for the leg of a table comprising a basemember having a foot portion adapted to be secured to the floor and toform a rest for the lower connection with the sleeve, a shaft carried bythe bracket, the table leg havinga side opening into which the shaftextends, the opening being arranged to accommodate the movement of thetable leg, and a gear connection between theishaft whereby the firstmentioned shaft is operated through said sleeve to raise and-lowerthetable leg.

In testimony whereof we aflix our signatu'res.
